Methods and limitations of assessing new noninvasive tests: part I: Anatomy-based validation of noninvasive testing.
The introduction and dissemination of new technology provide the potential for enhancing and expanding our understanding of disease processes (eg, atherosclerosis, myocardial dysfunction) and extending our treatment options while providing a tool for monitoring therapeutic responses.1,2 However, the growth of cardiac imaging has profound cost implications that will be exacerbated if newer techn...
متن کاملMethods and limitations of assessing new noninvasive tests: Part II: Outcomes-based validation and reliability assessment of noninvasive testing.
Outcomes-based approaches are the preferred methodology for technology validation. As discussed in part I of this review, the difficulties of performing an unbiased diagnostic evaluation are increasingly appreciated.1 An outcomesbased approach is advantageous in that it mimics the clinical application of testing. By risk stratifying patients, the results of this approach can be applied directly...
متن کاملon the comparison of keyword and semantic-context methods of learning new vocabulary meaning
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
15 صفحه اولLimitations of noninvasive testing in assessing the "occluded" carotid artery.
Over a 3 year period eight cases of atherosclerotic pseudoocclusion were detected by carotid angiography. The diagnosis was based on the detection of a thin, delayed antegrade trickle of contrast medium distal to an area of extreme stenosis. In six of these cases both direct and indirect noninvasive tests were interpreted as showing total occlusion. In one case these tests were thought to demon...
متن کاملWill noninvasive methods surpass invasive for assessing gametes and embryos?
The need to identify the most viable embryo following in vitro fertilization (IVF) was established early in the history of human IVF. The stalwart of identifying the best embryos has been morphology. Other techniques have however seen wide acceptance, including the use of preimplantation genetic screening, even though concerns exist over the invasive nature of the technique. Alternatively, noni...
